What are the three objectives of an OS design?
OS can be thought of as having three objectives. These are: Convenience: It makes a computer more suitable to use. Efficiency: It provides the computer system resources with efficiency and in easy to use format.
What is operating system software?
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.
What is operating system and its components?
An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.
What is structure of OS?
An operating system is composed of a kernel, possibly some servers, and posssibly some user-level libraries. The kernel provides operating system services through a set of procedures, which may be invoked by user processes through system calls.
What are the four main functions of an operating system?

What is the main component of operating system?
The main components of an OS mainly include kernel, API or application program interface, user interface & file system, hardware devices and device drivers.
What are the two main components of an operating system?
What are the two main parts that make up an operating system? Kernel and Userspace; The two parts that make up an operating system are the kernel and the user space.
Is kernel a process?
The kernel itself is not a process but a process manager. The process/kernel model assumes that processes that require a kernel service use specific programming constructs called system calls .
How do you use process?
“We learned about the creative process in art class.” “I’m trying to understand his thought process.” “Buying a house is not a short process.” “We are guaranteed due process by the law.”
What are the goals of operating system?
Objectives of Operating System
- To make the computer system convenient to use in an efficient manner.
- To hide the details of the hardware resources from the users.
- To provide users a convenient interface to use the computer system.
What are types of operating system?
Most people use the operating system that comes with their computer, but it’s possible to upgrade or even change operating systems. The three most common operating systems for personal computers are Microsoft Windows, macOS, and Linux. Modern operating systems use a graphical user interface, or GUI (pronounced gooey).
